Greg knows that 10 x 25 = 250. When the teacher asks the class to multiply 20 x 25, Greg uses mental math to get the correct answer, which is 500. Explain how Greg probably used his knowledge of 10 x 25 = 250 to mentally solve 20 x 25.
Greg probably reasoned that 20 = 2 x 10. Therefore, the product of 20 x 25 is 2 times the product of 10 x 25. 2 x 250 = 500.
